Low cost High Performance Wireless Mesh Networks (2 students)
Much research needs to be done towards realizing high throughput in
wireless mesh network environments. Current mesh networks deliver poor
throughput in multi-hop settings. We are currently investigating
different research challenges in the space of multi-radio and
multi-channel mesh networks. In 715 Broadway, we have deployed a 12 node
wireless mesh network where each node has multiple radios. This testbed
is supposed to be a multi-radio multi channel testbed where one can
potentially set different rafios to different channels to improve
throughput. Currently, we have 2-3 students working on this project. As
part of the course project, the students would be performing a detailed
measurement student in this testbed to instrument the performance under
different configurations. The goal is to use this measurement to
determine the design principles for constructing high performance
Cell-phone based Health care records system (2 students)
This project would involve developing a simple electronic medical system
(note, a simple database not a fullfledged EMR system) in a programmable
cellphone environment. Here, the goal is to have a setting where
healthworkers in the field collect health records on a cell phone and
these records are synced up with each other using SMS. The only means of
communication between the server and the cellphone will be an SMS
message. The challenges are how one would compress health care records
into small set of SMS messages, how one would maintain local state to
propagate Delta changes (instead of entire records), how to search
efficiently across cellphones etc.
Cell-phone based Financial Transaction System (2 students)
A cell phone based financial transaction system is supposed to provide
the flexibility of executing financial transactions in an intermittent
environment with lazy updates using SMS with the main server.
One student, Michael Paik, is working on a cellphone based financial
transaction system to support ATMs and Microfinance applications which
supports "low-cost authentication" and the ability
to provide "offline transactions" for financial transactions. Here
again, the means of synchronization between the server and the clients
would involve using only SMS. The student will work with Mike in the
development of the system.
Automated Diabetetic Retinopathy Detection (2 students)
One student, Koray, is working on an automated system to detect diabetic
retinopathy from retinal images using machine learning algorithms. The
basic system has been built - however several engineering
mechanisms + configuration testing is essential to make the system
robust and perfect. The current system still has a high false positive
ratio. The student will work in Koray in improving the robustness of the
algorithm and reduce the false positive ratio of the detection system.
Low cost paper Watermarking (1-2 students)
In the previous semester, a few students build a basic approach towards
extracting speckles in paper to show how one can watermark paper using a
simple USB microscope. The student(s) will work with some members of the
group to improve the system to develop a full fledged watermarking system.
Medical Education Modules (3-4 students)
This projects which contains two parts involves the creation of medical
education modules for teaching health-care workers in rural places about
specific diseases. The specific focus for these medical modules would be
two topics: (a) malaria and infectious diseases; (b) obstetrics. Here,
the student(s) would take up a specific topic and work with experts in
NYU Medical School on the creation of medical education modules for
their chosen topic. This project will build upon the WiSe-MD that has
already been developed in NYU for surgical education.
Intermittent Content Distribution (2-3 students)
This project would involve building a simple content distribution
network that operates in intermittent environment. An intermittent link
is one that is off and on. The goal here is to build an intermittent
proxy that can intelligently implement "store and forward". Jay Chen, a
PhD student, is currentlyw orking on a generic intermittent proxy
implementation. The students working on this project will work with Jay
on extending his proxy implementation to support content distribution
network. The medical education modules developed by the other group will
be the content that will be used for testing for this intermittent CDN.
Low-bandwidth Video Streaming (2-3 students)
This project involves building a low-bandwidth video streaming system
that can be used for video conferencing and one-way video streaming
(like MPEG). The goal is to get the streaming to work over 64 Kbps and
22 Kbps GPRS links. Some of the challenges in building such a system
would involve: (a) need for a proactive recovery system that can recover
important packets in the stream over a lossy link;
(b) developing a video codec that is applicable for low bandwidth
environments; (c) doing optimizations in static video environments
(background roughly fixed). There is a team of 1-2 students already
working on this. The group would work with this team.
Traffic Signaling System (2 students)
Road traffic systems in developing countries are perenially congested.
David Bindel and I have been working on developing an alternate
signaling protocol that internetworks the traffic signals to improve the
overall throughput of the road system. This project would involve
building a traffic simulator that can test some of these ideas and
improving over them. If successful, we can get traffic data from
developing countries to test this hypothesis in greater detail.
User Interface Design (2 students)
Researcher in MSR India have developed a text-free interface for
semi-literate and illiterate people in developing countries. This
project would involve coming up with alternative user interface designs
(especially for cell phones) that can are usable for semi-literate or
illiterate people. This is a very good challenge for design students.
Developing the correct interface can be a very good research challenge.
